  • the control unit 18 thus operates the print head assembly 12 to apply radiation-curable ink to the substrate 11 during the movement in the opposite directions along the guide (along the X-axis). Additionally, the apparatus 10 is configured to carry out double-stage UV curing of the printed ink.

  • curing units 16A and 16B may be kept at the same fixed distance from the print head assembly (for example, a distance of about 10- 15cm). Alternatively, each of these units may be displaceable with respect to the print head assembly: For example, when printing in the positive X-direction is carried, curing unit 16B is brought close to the print head assembly, and the curing unit 16A is displaced from the print head assembly a predetermined distance (e.g., a distance of about 70cm), while during the printing in the negative X-direction, unit 16A is located close to the print head assembly, and unit 16B is displaced therefrom said predetermined distance.

  • the present invention provides for on-line gloss control of inkjet printed images to achieve improved adhesion, better drop shaping and better shrinkage properties. This is implemented by controlling the delay time between the application of the ink (printing) to a certain location on the substrate and curing the printed ink, and also by controlling the amount of curing energy and wavelength of the curing radiation. With typically used single-stage curing, the printed ink is irradiated with high intensity UV radiation and the resulting images normally have a matte finish.
  • the present invention utilizes a double-stage curing: the first-stage curing - energy with relatively low intensity and long wavelength irradiates the ink droplet that was applied to the substrate, and the second, delayed curing stage - higher amount of energy with shorter wavelength irradiates the same droplet after a certain time period from the first-stage curing.
  • Figs. 2A-2B illustrate the results of the first- and second-stage UV curing, respectively.
  • Ink droplets, while formed and jetted from the print head 12 are high speed, causing development of negative pressure close to the surface of the ink droplets. Hence, atmospheric air (including oxygen) is drawn into the droplet.
  • the enclosed oxygen interferes the polymerization of the radical chains, thus causing low-dose, long-wavelength curing to be sufficient and virtually effective for gelling the bottom of the jetted droplet while leaving the surface of the droplet fluidic and uncured. Curing the bottom of the droplet controls spreading and improves color density and resolution, while delaying the surface curing of the ink drop results in a smoother drop surface which gives rise to glossiness..
  • the curing method of the present invention also advantageously provides creating symmetrical curing, and as a result symmetrical drop shapes are produced, thus minimizing the common problem of banding phenomena that appears in the printed and cured image, because of simultaneous bi-directional one-step curing (which leads to un- symmetrical completely cured drop shapes.

  • a curing beam first passes through the beam splitter 24 that splits the beam into first and second radiation portion at a predetermined power ratio and possibly also wavelength difference.
  • the first radiation portion propagates towards the mirror 20 that selectively reflects it to mirror 19A or 19B to thereby impinge onto print line B.
  • the second radiation portion propagates towards mirror 26 that reflects it to line A on the substrate.
  • the substrate may be made of any suitable material that is compatible with the selected inks.
  • suitable substrates include both porous and nonporous materials such as glass, wood, metal, paper, woven and non- woven, and polymeric films.
  • the films can be clear, translucent, or opaque.
  • the films can be colorless, a solid color or a pattern of colors.
  • the films can be for example transmitting or reflective.
  • the substrate can be fed into the printing apparatus by using any of the known feeding systems, e.g. the so-called "roll-to- roll” or "flat-bed” systems.
  • the UV-radiation source (a traditional UV light source with focusing and collimating optics, or a UV laser) can be adapted to emit radiation with predetermined intensity and wavelength.
  • the printing apparatus can be equipped with an intensity and wavelength controller for providing curing radiation with varied intensities.
  • the curing assembly may be equipped with additional elements such as filters, for filtering out unwanted energy components (e.g. visible light, infra-red radiation).
  • the required time delay between the printing and curing process, as well as between the first- and second-stage curing processes is controlled by the distance between the printing and curing locations. Additionally, the control unit is preprogrammed to control the time delay, and intensity and duration of the first and second curing stages, and to control the movement of the mirror and/or the radiation source to synchronize it with the movement of the print head assembly.
  • the present invention is particularly suitable for use in combination with a drop on demand process but, of course, may be used in combination with other ink jet printing processes, either continuous or intermittent.

Abstract

L'invention concerne un procédé et un dispositif pour imprimante numérique à jet d'encre. On applique en continu une encre séchable au rayonnement en des points successifs sur un substrat le long d'une ligne d'impression qui s'étend en travers du substrat. Simultanément à cette application, un premier rayonnement de séchage de première intensité préétablie est appliqué en continu sur l'encre appliquée aux points successifs susmentionnés, avec un certain retard, constant pour tous les points considérés, entre les applications d'encre et l'application du premier rayonnement de séchage. On applique ensuite un second rayonnement de séchage de seconde intensité préétablie aux mêmes points, pendant un certain temps, constant pour tous les points en question, après l'application du premier rayonnement décrit.
